The pale wax of the candle symbolizes Christ’s flesh, his sacred humanity. The wick, embedded in the center of the candle, represents his soul. The flame, as it burns down the wick, consumes the wax to give us light. It burns, expending itself, sacrificing itself, just as Christ sacrificed himself. The burning candle is aesthetically pleasing, and it gives a sweet aroma as it burns, another reminder of the presence of our Lord.
